This adds a helper function for reading the rotation (panel
orientation) from the device tree.

This function should better spell out why it talks about rotation versus
orientation.
It happens that orientation, due to bad design choices is named rotation
in DT.
But then this function is all about orientation, that just happens to be
named rotation in DT.
And the comments associated to the function should reflect this.
something like:
/**
* of_drm_get_panel_orientation - look up the orientation of the panel using a
* device tree node
* @np: device tree node of the panel
* @orientation: orientation enum to be filled in
*
* Looks up the rotation property of a panel in the device tree.
* The orientation of the panel is expressed as a property named
* "rotation" in the device tree.
* The rotation in the device tree is counter clockwise.
*
* Return: 0 when a valid orientation value (0, 90, 180, or 270) is read or the
* rotation property doesn't exist. -EERROR otherwise.
*/
This would at least remove some of my confusiuon.
And then maybe add a bit more explanation to the binding property
description too.

I'll clear this up in the next patch set.

Tried this, yet I got told off for adding kernel details to the DT
documentation (which is frowned upon).

Devicetree systems can set panel orientation via a panel binding, but
there's no way, as is, to propagate this setting to the connector,
where the property need to be added.
To address this, this patch sets orientation, as well as other fixed
values for the panel, in the drm_panel_attach function. These values
are stored from probe in the drm_panel struct.

Should probably put these in a struct to ensure the connector and
panel have the same data types. Will do in a following patch if we
stay with this.

split the drm_connector_init_panel_orientation_property into two
functions. One for platforms without the need for quirks, and the

Otherwise this patch looks good, with this fixed you can add my:
